I'm on Fastmail and it has been worth every penny. They happen to also integrate their email alias generation with 1Password, which I also use, making it an extra good investment
Despite their name being fastMAIL they also have a passable calendaring implementation. My only complaint about it is that they don't offer an Android "widget" in order to see the upcoming agenda at a glance, so one has to actually launch their app to view the calendar
If such things matter to you, they have CalDAV and WebDAV offerings, the latter of which I use for backing up my ViolentMonkey scripts. I haven't used their "Google Keep" replacement because Joplin serves my needs, but it does exist. And all of this for the same yearly price
